CHECK LINK.

Application;;filed March 22, 1920;- Seria1-No.E3G7,609.=

T0 allt' whom it may concern:

Be-Hit. known that I, HARRY S.- BERGEN, a I

citizen of the-Uni-ted.States, resiclin at Toledo, in the. county of Lucas and btateof Ohio, have invented; certain new and useful; Imp-rovements-,= in, Check @Links, of

which-the following isa specification;

This invention relates 'to scales and parthe-lever is usually provided with a pair of load V-pivots, .thenxesL of. which; are !1n,alignment and parallelito they pivotal axis of the lever-fulertunr Thecplatter is supported upon these load pivots, and in order to preventthe platter and spider; fromrtoppling fore or, aft: the.,spideiis) provided with a a stem which extends downwardly and is connected by meansiofia check link to a member rig d with the; scale frame.

Oneof the objects, of; my invention is to, provide such a link-,connection in which frictiorris reduced tCX-fl minimum- Anotherv object is to provldea device of this; kind: which is comparatively inexpensive-and is easily assembled and ad-,

justed.

Otherobjects and advantages will be ap parents from the following description, in

which reference is had to the accompany-V ing drawings illustrating a preferred e mhodimenti, of my invention and; in ,WlllCll;

Since my inventionrelates solely to means for preventing the platform and spider from tilting, I haveshownionly so much of the other scale structure as will suflice to show the connection of my invention therewith. The portion of the scale frameshown in Figure; 1 comprises a base housing. 1 ,iupon whichiis rigidly secureda base-horn 2-,the tipscof the base horn beinganotched toirecei-vebearings 3 of 1 agate or other hard -ma-; terial. The -main lever rol the scalelcarries a qpairrof alignedfulcrum pivotsq (only one of which can be seen inthe drawing), the,-pivots-,5 beingrockably carried uponthe bearings 3. The lever l is also provided with ;a pair; of aligned knife edge pivots 6 located; a short distance rearwardlyof the pivots 5.;a-nd; supporting aplatter spider 7 which carries apa-ir of'inverted bearings-8 1 rockably--resting upon the-aligned edgesof upon a spider having, bearings which rest:

of! which carries a coimecting plate 11.

The plateyll is provided at its, upper edge with a threaded-boss 12 receiving the. lower end of thestem 9 and near; its lower edge with=a pair of rearwardly-projecting,conetipped pins 13,;the purpose ofnvhich will flaps pear later. Detachably secured-to the, rearward;face;of.-the plate 11' is a U-shaped mem-v ber 14, the "bight-wportion of which. carries a forwardly-projecting-conetipped pin 15 Similaarkin; shapeto the pins; 13.

Secured within the base housing 1 directly beneath the base hornQ is ;a b'raoket16, the horizontal portion of which is provided with a: pair of: threaded: holes 17 receiving'v-set screws 18 and apair ofunthreaded-holes 19 receiving cap 'screws 20 which a-reserewed into the under surface ofthe; base housing, asshown-in Figure 1. By; loosening one of the set screws 18 and tightening the other thebracket'may be swung forwardly or rearwardly, and by loosening'one of the cap screws 20 and tightening the other the bracket may be swnnglatera-lly, while vertical adjustment; of the-bracket may be attained by loosening both setv screws and tightening both cap screws, and'vice versa.

The downwardly-extending arm 21 of the bracket. 16 carries a pair of forwardly-pro-v jecting cone-tipped pins'27 similar in shapeto the pins13 carried by the plate 11, and secured to the forward face of the arm 21 is a U-shaped member the bightj portion of which carries the rearwardlyextending 7 being in all respects like the U-shaped memher 14.

For the purpose of pivotally connecting the plate 11 and the bracket 16 I have evolved a link 28, the upturned ends 24 of which contain inwardly-opening coneshaped recesses or sockets 25 to receive the pins 13 and 27 and outwardly-opening coneshaped recesses to receivethe pins 15 and 23, said upturned edges 2 falso having notches to receive the legs of the U-shaped members 1e and 22.

In assembling the device the link 28 is applied to the bracket 16, the pins 27 engaging the cone-shaped recesses 25 at one end of the link, and theplate 11 is then swung '(withthe pivot 6 as a center) to bring the pins 13 into engagement with the recesses 25 at the other end of the "link 28. The U- shaped members 1 1 and 22are then applied respectively to the plate 11 and bracket 16 with the pins 15 and 23 engaged inthe recesses 26, the U-shaped members being secured to the plate 11 and bracket 16 by screws or other fastening means. When the U-shaped members 14 and 22 are in place, the pins 13 and 15 and the pins 23and 27 are in alignment so that they form practically frictionless pivotal connections between the parts 11, 21 and 28.

From the foregoing it will be seen that I have provided a simpleand efficient check link. Since the bearing surface of each of the pins (which may, if desired, be made adjustable) is substantially a mere point, these surfaces'are easily brought into alignment and the friction due to rocking of the pins in the cone-shaped recesses incident to movement of the scale in weighing is so slight as to be negligible.

While it will be apparent shown is well calculated to adequately fulfill the objects primarily stated, it is to be understood that the invention is susceptible to variation, modification and'chan'ge within the spirit and scope of the subjoined claims.

Having described my invention, I claim:

1. A check link connection for weighing scales comprising, in combination, a member having oppositely extending pointed pins thereon, the points of said pins being in alignment in a direction substantially perpendicular to the axes of said pins, and a check link having oppositely opening recesses in its end, said pins being received in said recesses.

2. A pivotal connection comprising, in combination, a plate, a pair ofpointed pins projecting from one face thereof, a U- shaped member secured to said plate, a pointed pinfextending from the bight of,

4-. A pivotal connection comprising, in combination, a plate, a pair ofpointed pins projecting from one face thereof, a U- shaped member secured to said plate, a- I pointed pin extending from the bight of said U-shaped member toward said plate, the points of said pins being in alignment, and a member-having a flange, said flange having recesses in the opposite sides thereof, said pins being received in saidrecessesr 5. A link connection comprising, in combination, a pair of plate-like members each having a pair of pointed pins projecting therefrom, a U-shaped member secured to each of said plate-like members, pointed pins projecting from the bights of said U- shapcd members, the points of the pins on each plate-like member and the U-shaped members secured thereto being in alignment, a link, and flanges at the ends of said link, said flanges having notches receiving the legs of said U-shaped members and recesses receiving said pins. 6. In a weighing scale, in combiiiatioma frame, arlever fulcrumed thereon, a com- .modity-receiver supported on said lever, a

plate connected to said commodity-receiver, a. pair of pointed'pins projecting from one face of said plate, a U-shaped member secured to said plate, a pointed pin extending from the bight of said U-shaped member toward said plate, the points of said pins being in alignment, and a member having a series of recesses therein, said pins being received in said recesses, said member being pivoted to said frame.
